Hearing noises from your auto regularly is never comforting, so hearing noises on your Cadillac DTS suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a small problem as well as a warning of a much larger repair to come. In any case, it is important to check the origin and take the necessary actions to resolve the problem, it is with this objective in mind that we wanted to write this article to help you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, after that, what can be the cause of a squeaking noise when a speed bump is being passed and finally what to do if you have another noise when a speed bump is passed.
Suspension cracking noise Cadillac DTS
Check Cadillac DTS suspension
If you experience a suspension noise when you pass a speed bump on your Cadillac DTS, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To examine if this is the problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of swapping them as soon as possible or you may affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Cadillac DTS suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a sound when they are in torsion. To examine this, you can try both types of torsion, first vertical with suspension compressions on the speed bump passages, and horizontal when you are going to turn at low speed. If it cracks in these two cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Cadillac DTS, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Cadillac DTS passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you vary direction. If this is your situation, the parts that may have been damaged by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to examine it, place it under the vehicle and apply twists on each of its elements to examine that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your technician or replace them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Cadillac DTS, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Remember to examine by going under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case disassemble them from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Cadillac DTS. To replace them go to your auto mechanic.
Other speed bump noise Cadillac DTS
If, despite all its assumptions, you still can’t find the origin of the noise your Cadillac DTS makes when you pass a speed bump, we suggest you to consult this content on a loud noise on Cadillac DTS or to visit your technician in order to carry an in-depth check on your Cadillac DTS and find this problem.
